(EN) COLOUR PIXEL CONFIGURATION FOR AN AUTOSTEREOSCOPIC DISPLAY
(FR) CONFIGURATION DES PIXELS DE COULEUR POUR UN AFFICHAGE AUTOSTEREOSCOPIQUE
Abrégé
(EN)
In an autostereoscopic display apparatus comprising a spatial light modulator comprising an array of colour pixels 1044-1058 arranged in rows and columns and a spatially multiplexing parallax element 1072 capable of directing light from successive columns of pixels 1044-1058 towards successive ones of plural viewing windows, the green pixels are arranged in every column of the array. The green pixels have an area which is of the order of half the area all the other pixels combined. Several different choices for the other pixels are possible including red and blue pixels interlaced along the rows and columns, interlaced red, blue and white pixels or interlaced red, blue and magenta pixels. Preferably the display apparatus is switchable between a first mode in which the spatially multiplexing parallax element is effective and a second mode in which the spatially multiplexing parallax element has no effect.
(FR)
Dans un appareil d'affichage stéréoscopique comprenant un modulateur lumineux spatial comportant un réseau de pixels de couleur (1004-1058) disposés en rangées et en colonnes, et un élément parallaxe de multiplexage spatial (1072) capable d'orienter la lumière à partir des colonnes successives de pixels (1044-1058) vers des colonnes successives de plusieurs fenêtre d'observation, les pixels sont disposés dans chaque colonne du réseau. Les pixels verts possèdent une zone qui est de l'ordre de la moitié de la zone de tous les autres pixels combinés. Plusieurs choix différents d'autres pixels sont possibles, y compris les pixels rouges et bleus imbriqués le long des rangées et des colonnes, des pixels rouges, bleus et blancs imbriqués ou des pixels rouges, bleus et magenta imbriqués. De préférence, l'appareil d'affichage peut commuter entre un premier mode dans lequel l'élément parallaxe à multiplexage spatial est efficace et un second mode dans lequel l'élément parallaxe à multiplexage spatial n'a pas d'effet.
